Method for separation of nitrogen and carbon dioxide by use of ceramic materials as separating agent

摘要

The invention provides a method for the separation of nitrogen and carbon dioxide at elevated temperatures by using a ceramic separating material. The ceramic may be selected from sepiolite in the unmodified form, sepiolite which has been heat-treated, and sepiolite which has had part or the whole of the exchangeable cation thereof replaced with zinc ion and which has been subsequently subjected to a heat treatment.
